Know what kind of feedback on your work makes you the most productive and what kind of feedback makes you defensive.
Providing feedback on design work is a delicate art. Too much, and the designer feels a loss of control. Not enough, and the designer may not get a strong sense of direction.
But feedback efficacy also depends on the packaging (delivery channel, tone) and the scope. You may get feedback at a level that’s too granular or too broad for where you are on the project.
Your reaction to feedback incorrectly packaged or scoped can set the tone for ongoing interactions. People rarely remember the circumstances or the content of the feedback and only remember the reaction.
